The patriarch, Don Panoz, PhD, lightly pressed the starter button, and within moments the deep rumble of the Esperante Spyder GT rendered silence, then there was a burst of applause from guests at the Thursday evening unveiling by Panoz LLC of its newest and 25th anniversary edition luxury sports car. The Spyder, along with an anniversary edition of its existing Panoz Roadster and Panoz GTR1, was three of a half-dozen exclusive sports and touring cars from the auto developer, under the admiring gazes of a showroom filled to capacity with guests from all public and private sectors. It was about time, was the general consensus.
